2. Set the F-90 power on
configuration setting to 1 (CV
control – Ext voltage).
Be sure to cycle the power after the power on
configuration has been set.
3. Press the Function key and confirm
the new configuration settings (F-
90=1).
4. Press the Output key. The voltage
can now be controlled with the
External voltage.
The input impedance for external voltage control is
10kΩ.
Use a stable voltage supply for the external voltage
control.
CV and CC Slew Rate Priority are disabled for V-I
mode (F-03) when using external voltage control.
See the normal function settings on page 108.
Ensure no more than 10.5 volts are input into the
external voltage input.
Ensure the voltage polarity is correct when
connecting the external voltage.
